BASE FOR FURNITURE.

SPECIFICATION forming part of Letters Patent No. 561 ,7'45, dated June 9, 1896. Application filed May 6, 1893. Serial No. 473,204. (No model.)

To all whom it may con-corn:

Be itknown that I,\VILLIAM F. WooDRUrF, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Bases for Furniture, of which the following is a specificat-ion.

This invention relates to that class of bases for furniture in which the article of furniture has a pivotal connection with the base and by its oscillatory movement a support is moved out in position to receive it in order that it maybe revolved to bring the bed to the front.

111 the accompanying drawings, Figure 1 is an isometrical representation of myimproved base in which an under side view of the platform is seen. Fig. 2 is an isometrioal representation of the base in which the movable supports are in their extended position. Fig. 2 is a fragmental view of the parts 10 and 11. Fig. 3 is a plan view showing the operative parts in dotted lines and in their closed position. Fig. 4. is also a plan view in which the movable supports are in their extended position and receive the platform. Figs. 5 and 6 are views of the mechanism for operating the movable supports.

The base proper, 1, is of rectangular form, its front edge provided with two quadrantshaped openings 2 and a transverse central guideway 4, its rear edge having a groove 3, the ends of which are inclined. XVithin the quadrantshaped openings 2 are located two quadrant-supports 5, having a pivotal connection with the base proper at 6, and from their face fall depending legs 7, to the under side of which are secured rollers or casters 8. 'When the quadrants are in their closed positions, their front faces lie flush with the front of the base, the legs entering recesses 9. From the inner corner of the quadrants project studs 10, forming stops to the outward movement of the quadrants and during the movement of the quadrants traveling under the lower edge 11 of the curved side of the quadrant-shaped openings. The mechanism for operating the quadrants consists of a guide 12, seated in the guideway 4c and having a lengthwise slot 13, and cleats 14, secured to the base 1, hold the guide in the guideway.

To this guide are pivoted arms 15, which also have a pivotal connection with the quadrants 5. To the under side of the guide 12 is pivoted a latch 16. (Shown at Figs. 5 and 6.)

From the center of the under side of the platform 17 projects a pin 18, and to the under side of this platform is pivoted a link 19, having a roller 20 pivoted to its free end. The pin 18 is placed in the slot 13 of the guide 12, and the roller 20 is placed in groove 3 in the upper face of the base 1.

When the parts are in the position shown at Figs. 1 and 3, the pin 18 will be in the extreme inner end of the slot 13 and the latch 16 will surround its outer edge, as shown at Fig. 5.

If the platform be moved by taking hold of the end 21, the link 19 will act as its fulcrum, and the pin 18 pressing against the latch 16 and the free end of the latch against the inn er face of the guideway will cause the guide to move outward, and owing to its linked connection with the quadrants will move them on their pivots from the position shown at Figs. 1 and 3 to that shown at Figs. 2 and -i-, and when this position has been reached the free end of the latch will have entered the notch 22, formed in the base, and will occupy the position shown at Fig. 6, allowing the pin to move in the slot 13 without affecting the further movement or the quadrants. The platform is moved until the roller 20 comes in contact with the opposite end of the slot 3, and at this point the pin 18 will have reached the inner end of the slot 13 and the further movement of the platform will cause the guide to move inward,moving the quadrants on their pivots, drawing them inward into their closed position, and this movement will cause the latch to close around the pin, as shown at Fig. 5, in position to be again operated upon by the pin, and this is accomplished by the walls of the notch.

In depressions 23, formed in the upper face of the base 1, are located casters 2i, placed at proper intervals over its surface, and the quadrants are each provided with a similar caster 25.

The casters in the base are slightly higher than those in the quadrants, in order that weight of the article of furniture located upon the platform will be borne by the base.

It will be noticed that the under side 11 of be noticed that the quadrant-supports are in their extended position before any of the weight of the platform is transferred thereto and that the weight is whollyremoved therefrom before they are moved totheir closed position, which enables the quadrants to be operated withthe least possible power.
